:Briefly described, myv invention consists in a castimetal body: B,having a main'bore Bv longitudinally formed therein adapted to receivethe valvebody carry-v ing a valve Y, and held in place by means of acap" C which operatively supports; an op erating member z w i 'ThebodyjBhas a flangedlower endpon tion '6 adapted to abutagains't 'thejtop" of abasin or other supporting device," and an elongated stem bv integralwith the body and extended substantially therefrom. The

stem' 12' hasan inlet passagelv which communicates witha chamberuFinwhich-is held the smaller cylindrical portion a of the member A..

t The upperrend of the body B internally threaded to receive anextension from the" and cap G, by means of which the clian'ib'er1B"holding the member A, is closed. The valve body A has a conical valveseatG formed therein'adapted to engage acor'responding lycformed-portionon the valve V, and the valve stem V is slidably held a boss a formed onthe member A. 1

Member Alias anoutle't passage H which registerswith audelivery' passages' of a spout S formed integ'ral with the body.

Member A is stationarilyheld in the body B by nieans'of' a ke'y formedth reon;

in a 'bore h of which engagesa correspondingly formed key-way lengthwiseWill'be noted by referen'ce to Fig.;1", that' whenthe member Ais-"properly positioned" in the faucet body, the lower end of cap Cengages the upper end of the mr'enibe'r and'provides a chamber E abovetheiipfier end of member A, andwithin the"cap"C:

The operating member O has astem' O with an enlarged headd thereon,which o'p-' erates below a threaded recess D" in""the upperportion' ofcapC. When th'evalve V is closedth'ehead dais adapted toabutthe; upperend of the valve stem V and when the operating member Ois presseddownwardly, said head serves to urge thevalve down-* wardly against thepressure of the masses as to permit a flow'of 'waterthrough 'the valveseat, the i case the member 0 will not necessarily turn when it isrestored to' normal'position and" the valve is closed. I 7 It will beobserved-by referenceto Figs. 1, 3 and 4 that the chamber F in thelower-I portion of the body isjslightly larger than the portion aofmember A, so that water o f 'the chamber B. It 7 so passageH and thepassage S As indicated in Fig; 3, the cap mayhave from the inlet passageI will fill the chamber F around the portion a.

The walls of the chamber a are provided with one or more peripheralports as at f, f, for afiording communication between the chamber F, andan inner chamber F within the member a inwhich the valve V is seated.The positionsof the ports f, f, is such that when the valve iscompletely open the water will fiow'through said ports, and thencethrough the valve seat and outwardly through the passages H and S, thehead of. the valveserving to close said ports prior to the completeclosing of the valve V. I

Thus, as shown in Fig. 5, when the ports f, f, areclosed a water cushionwill be. provided below the valve seat and above the head ofthevalve,:which will prevent the forcible 1 impact of the valve against itswill be closedagainst the entrance of water 1 to the passage F prior tothe closing of the" valve, as shown in Fig. 5, and. also when- 55.

seat and a consequent pounding which would be effected thereby.

The pressure of he Water subsequent to the closing of the ports. f, 7",will force water through a small inlet 2' in adetachable end closure A,which is threaded into the lower end-of the cylindrical portion a. Whenthe chamber F is completely filledthe pressure therein will be equal tothe pressure in the passage I, and the valve will be gradu allyclosed,,the water serving as a cushion between the valve .and its seat,gradually leaking into the passage H between the wall of said passageand a reduced extension on the valve.

The upper end of the member A adjacent the spout S has a shallowpassage'e which affords communication bet-ween the chamber E andthe'spout, so that at all times any water which may leak into thechamber E may bedrawn outwardly. through the spout S due to the suctioncreated therein when the faucet: is discharging.

vent or impair the operation of the member 0 for opening the valvea"Asshown in Fig. 4, when the valve is completely open the water willflow freely frompassage I and chamber F, through ports 7", f, valve seatG, and outwardly through the passage H and the spout S. The ports f, f,are positioned so that they the valve is closed completely as shown inFlg. 1.

The operation of the faucet for discharging water from the spout thereofrequires only the depression of the member 0 and stem 0, so that it willforcibly engage the stem V and move the valve V downwardly in the"chamber F against the pressure of the water, until the upper end of thehead of the'valve is moved below the ports f, 7.

- As long as the members 0 and V are held This prevents any backpressure which may. ordinarily pre-v in their depressed position, thefaucet will continue to discharge water. Immediately, however, upon therelease of the member 0, the pressure of the water in the chamber F willserve to move the valve upwardly into WVhile I have shown anddescribedbut one 7 form of my invention, it will be understood that Imay change or modify thesame within the scope of the appended claimswithou departing from the spirit thereof; What I claim is: '1.
